I installed a new tensioner and this belt on a 2006 Acura MDX that was chirping and squeaking. I thought I could still hear the occasional chirp but this was much better. After about 100 km of driving, there was a terrible squeak again. I tried the water trick with the strap to see if it was the strap that was causing the squeak. I tried the 303 aerospace protection on the belt which only lasted a couple of days. I finally have a real Acura belt, which unfortunately only costs $70. The squealing didn't come back for several weeks.
